Question

A man runs at the speed of 15 km per hour how much time will he take to cover 750 meters​

Answer 1

Answer:

$speed =15 {kmh}^{ - 1} \\ = 15 \times \frac{5}{18} {ms}^{ - 1} \\ = 4.16 {ms}^{ - 1}$

$speed = \frac{distance}{time} \\ time = distance \times speed \\ time \: = \: 750 \times 4.16 \\ time = 3120 \: seconds$
