Question

Kristin runs from 3.50 pm to 4.20 pm at an average speed of 7 kilometers per hour. How far did she run?

Answer 1

$\large\fbox\red{Answer}$

Given,

• Time = 30 mins = 180 secs

• Speed = 7 km / h = $\sf\:7 \times \frac{5}{18}$

Distance = speed x time

$distance = 7 \times \frac{5}{18} \times 180 \\ \\ = \frac{35 \times 180}{18} \\ \\ = \frac{35 \times 10}{ 1} \\ \\ = 350 \: mts$

Distance = 350 mts Or 3.5 kms.
