Question

A bike moves 1km in 13 minutes and 5 km in 2 hours and 30 meters in 13 minutes calculated the Average speed​

Answer 1

Explanation:

S1 ( distance) = 1 km

T1(time) = 13 min

S2 (distance) = 5km

T2(time ) = 2hour 129 min

S3 ( distance) = 30metre = 144 km

T3 (time) = 13 min

average speed= total distance/ total time

= 1+5+144/13+129+13

= 150/135km/min
