Option "A" is the correct answer.

Number of truck and car in parking is 64 , 80

Step-by-step explanation:

Given:

Sample ratio = 4 truck and 5 car

Find:

Number of truck and car in parking

Computation:

Sample ratio = 4 / 5

So,

Option 1

64 truck 80 cars

ratio = 64 / 80

ratio = 4 / 5

Option 2

72 truck 73 cars

ratio = 72 / 73

84 trucks 100 cars

ratio = 84 / 100

ratio = 21 / 25

96 truck 110

ratio = 96 / 110

ratio = 48 / 55

sample ratio match with option 1

So,

Number of truck and car in parking is 64 , 80

answer: 457.14

step-by-step explanation:

205 - 45 = 160

160 / .35 = 457.142857

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
