Answer 1

Answer:

as, speed=distance/time

so, distance =143km (given)

time =2h 36min =2h+36/60h=2h+3/5h

hence, time=13/5hrs

so, speed =143km/13/5hrs

S=55km/hrs

Answer 2

Answer:

Speed = 55 kmph

Step-by-step explanation:

Speed = Distance / time

Michael drives 143 kmfrom town A to town B in 2 hours 36 minutes.

=> D = 143km,

t = 2 hours 36 minutes = 2 36/60 = 2 3/5 = 13/5 hr

Speed = 143 / 13/5 = 143 x 5 / 13 = 11/5 km/hr

.•. Speed = 55 kmph
