the first car is 70 kmh and that of the second car is 90 ms.
(1) Which car is moving faster
(10) What is the distance benveen the cars after I hour 15 minutes​

Answer 1

Answer:

the answer is given above

Answer 2

Answer:

1) second car is moving faster.

2) 317.5 km

Step-by-step explanation:

1) speed of car 1 = 70 km/h

= 19.44 m/s

speed of car 2 = 90 m/s

therefore after observating the speeds of the cars, we saw that --------

Car 2 is moving faster.

2) After 1 hour 15 minutes

Distance covered by car 1 = speed × time

= 70 × (1 h 15 min)

= 70 × 4500 (sec)

= 3,15,000 m

= 315 km

Distance covered by car 2 = speed × time

= 90 × (1 h 15 min)

= 90 × 4500 (sec)

= 4,05,000 m

= 405 km

thus,

Distance between the cars after 1 h 15 min

= (405 - 315) km

= 90 km

hope this helps you !!!!!!!!!
