Question

the speed of truck is 324/8 km/hr find the distance cover by the car on 40/36 hour​

Answer 1

Answer:

it is 324/8 ×40/36 that is 45 km

Answer 2

Answer:

(ii) 25 km  

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
