Question

A car moves at a speed of 40 km/hour for 15 minutes and then at a speed of 60 km/hour for the next 15 minutes. calculate the total distance travelled by the car​

Answer 1

Answer:

25 km

Explanation:

Speed (s1) = 40km/h

Time (t1) = 15 mins = (15/60) hr

Distance d1 = (s1 × t1) = 40 × (15/60) = 10 km

Speed (s2) = 60 km/h

Time (t2) = 15 min = (15/60) hour

Distance (d2) = (s2 × t2) = 60 × (15/60) = 15 km

Total distance (d) = (d1 + d2) = 10 km + 15 km = 25 km

Answer 2

Answer:

the distance travelled is 3000km

Explanation:

distance = speed ×time then 40km +60km = 100km

15minutes +15 minutes = 30 minutes

distance equal to 100 × 30 = 3000
