A car travels for 3 hours 15 minutes. Its average speed is 80km/h. Work out the total distance the car travels.

1 hour=60 minutes].

Step-by-step explanation:

speed×time

80×3hours and 15min

(3hours)

15÷60=0.25hours

3.25h

80×3.25=260

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

69.64%
