Answer:
(a) 2.5 hours , (b) 60 km / h
Step-by-step explanation:
formula's we'll be applying:
- distance = speed * time
- speed = distance / time
- time = distance / speed
here given it takes 3 hours at a speed of 80 km/h to travel to town B
then using the equation above lets find the distance,
distance = 3 * 80 = 240 km from town A to town B
( a )
asked how many hours would it take to travel Town A to B at a speed of 96 km/hr
so time = distance / speed
= 240 / 96
= 2.5 hours
( b )
asked what's the speed if it took 4 hours:
speed = distance / time
speed = 240 / 4
speed = 60 km/ h
