Answer 3

Delivery Time for a Carrier Pigeon

To determine if a carrier pigeon can deliver a message over a distance of 130 km in a given time, we need to calculate the time it would take for the pigeon to travel that distance at its given speed.

The speed of the carrier pigeon is stated as 50 km/h.

a) To determine if the pigeon can deliver the message in 2 hours, we need to calculate the distance it can cover in that time.

The formula to calculate distance is: distance = speed x time.

Using this formula, we can calculate the distance the pigeon can cover in 2 hours: distance = 50 km/h x 2 hours = 100 km.

Since the distance the pigeon needs to cover is 130 km, it will not be able to deliver the message in 2 hours.

b) To determine if the pigeon can deliver the message in 3 hours, we can use the same formula.

Using the formula, we can calculate the distance the pigeon can cover in 3 hours: distance = 50 km/h x 3 hours = 150 km.

Since the distance the pigeon needs to cover is 130 km, it will be able to deliver the message in 3 hours.

In conclusion, the carrier pigeon will be able to deliver the message in 3 hours, but not in 2 hours.
