Answer 1

Answer:

Kiran jogging at 6.2 miles per hour

Step-by-step explanation:

The following information is missing in the question:

Kiran and Clare live 24 miles away from each other along a rail trail. One Saturday, the two friends started walking toward each other along the trail at 8:00 a.m. with a plan to have a picnic when they meet.

The trip last 2.5 hours (from 8:00 a.m to 10:30 a.m.)

If Claire walked at 3.4 mi/h, the she covered a distance of:

speed = distance/time

distance = speed * time

distance = 3.4 * 2.5 = 8.5 miles

Therefore, the distance covered by Kiran was 24 - 8.5 = 15.5 miles. Then she jogging at the the speed of:

speed = 15.5/2.5 = 6.2 mi/h
