Question

скорость легковой автомашины 1200 м/мин. За сколько часов машина проедет: а) 144км б)36км в)8 км г)54км срочно надо!!!!!!!!!!!!!

Answer 1

1200 м/мин = 1200·0,001:  1/60 = 72км/ч

а) 144:72 = 2ч

б) 36: 72 = 0,5ч = 30мин

в) 8:72 = 1/9 ч = 60/9 = 20/3 мин = 6мин 2/3 = 6мин 40с

г) 54: 72 = 3/4 ч = 45мин

 

Answer 2

Calculating the Distance Traveled by the Car

To calculate the distance the car will travel at a speed of 1200 m/min, we can use the formula:

distance = speed × time

Let's calculate the distance for each scenario:

a) For 144 km: - Convert 144 km to meters: 144 km = 144,000 meters - Using the formula: time = distance / speed - time = 144,000 m / 1200 m/min

b) For 36 km: - Convert 36 km to meters: 36 km = 36,000 meters - Using the formula: time = distance / speed - time = 36,000 m / 1200 m/min

c) For 8 km: - Convert 8 km to meters: 8 km = 8,000 meters - Using the formula: time = distance / speed - time = 8,000 m / 1200 m/min

d) For 54 km: - Convert 54 km to meters: 54 km = 54,000 meters - Using the formula: time = distance / speed - time = 54,000 m / 1200 m/min

Calculations

a) For 144 km: - time = 144,000 m / 1200 m/min - time = 120 minutes

b) For 36 km: - time = 36,000 m / 1200 m/min - time = 30 minutes

c) For 8 km: - time = 8,000 m / 1200 m/min - time = 6.67 minutes

d) For 54 km: - time = 54,000 m / 1200 m/min - time = 45 minutes

So, the car will travel: a) 144 km in 120 minutes b) 36 km in 30 minutes c) 8 km in 6.67 minutes d) 54 km in 45 minutes
