Question

A Two cars start from the same place at the same time in the same direction. The speed the first car is 70 kmh and that of the second car is 20 m/s. (1) Which car is moving faster? 2
What is the distance between the cars after 1 hour 15 minutes?​

Answer 1

Answer:

1) second car

2) 2.5kms

Step-by-step explanation:

first car speed = 70km/h

second car speed = 20m/s = 20*18/5= 72km/h

therefore second car is moving faster

2) distance travelled by first car after 1 hr 15 min = 87.5km

distance travelled by second car after 1 hr 15 min = 90 km

then 90-87.5= 2.5 km is the distance between two cars after 1hr 15 mins
