Question

a car travels 174km in 3hrs a)how long will it take to travel 580km b)how far it travels in 7 1/2
​

Answer 1

Answer:

distance travelled by car in 3 hours = 174 km

distance travelled by car in 1 hour = 174/3 = 58 km

a) Now the average speed of car is 58 km/h ,so

distance to travel = 580 km

speed = 58 km

Time = distance/ speed = 580/58 =10 hours

b) Average speed =58 km

Time = 71/2 minutes

distance = time × speed = 71/2 ×58

= 35.5 × 58

= 2059
