Acar and a lorry started travelling at the same time from town r to town s. when the car arrived in town s, th lorry had only travelled 0.6 of the journey. the lorry needed 45 min more to complete the journey. the lorry travelled a constant speed of 60 km/h. find the distance between the two towns.

112.5 km

Step-by-step explanation:

The lorry needed 45 minutes to travel the remaining 0.4 of the journey and was traveling at 60 km/hr.

First, convert minutes to hours:

45 min × (1 hr / 60 min) = 0.75 hr

Now use distance equation:

distance = rate × time

0.4d = 60 × 0.75

d = 112.5

The distance between the towns is 112.5 km.

square pyramid

step-by-step explanation:

square prism looks like nothing like that

triangular prism has a rectangular base instead of a square base

tetrahedron has a triangular base

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
