Answer to Question #248000 in Physics for Rica

Question

1. A jeepney tried to over a car. The jeepney moves at 40km/hour convert this to the british system feet persecond?

2. It take about 8.o minutes for light to travel from the sun to the earth. How far is the sun from the earth in meter, in feet

Answer 1

1. 40 km/hour are 40 000 m/hour. Divide this number by 3600 to get meters per second:

$$v_\text{m/s}=40000/3600=11.11\text{ m/s}.$$

Next, we know that 1 m has 3.28 feet, which helps us convert the speed:

$$v_\text{ft/s}=v_\text{m/s}·3.2808=36.45\text{ ft/s}.$$
