minutes. What is his speed in km per hour?
(a) 3.6
(b) 7.2
(c) 8.4
(d) 10​

Answer 1

Answer:

Distance travelled=600

Time taken=5 min

Time taken in seconds=5×60=300sec

Speed=distance/time

600÷300=2m/sec

Speed in km/h=2×18/5

=36/5=7.2km/h

Answer 2

Step-by-step explanation:

speed=distance÷time

0.6÷(5÷60)

0.6×12

7.2
