Answer 1

Step-by-step explanation:

Given: A walks 7km in 2.5 hours B walks 250 meters in 5 minutes.

To find: Ratio of their speed

Solution: 7 km = 7000 meters

2.5 hour = 2.5x60x60 = 9000 seconds

A speed = 7000/9000 = 7/9 m/s

B speed 250/300 = 5/6 m/s

Ratio of speed of A:B = 7/9 :5/6

Ratio = 14:15

Hence answer is 14:15.
