Question

A cyclist covers 30 km in 90 minutes. Calculate his speed in both meter per second and kilometre per hour......​

Answer 1

Answer:

Dist. travelled = 30 km

Time taken = 90min = 1.5 hrs

Speed = 30/1.5 = 20 km/hr

= 20 × 5/18 m/sec

= 100/18 m/sec

= 50/9 m/sec

= 5whole5/9 (5 5/9 ) m/sec.
