Question

The speedometer of a European sportscar gives its speed in km/h. To the nearest integer, what is the car's speed in mi/h when the speedometer reads 282 km/h?

Answer 1

175
`(mi)/(h)`

Step-by-step explanation:

v = speedometer reading of a european sportscar =
`282 (km)/(h)`

we know that,

1 km = 0.621 miles

So the speedometer reading of a european sportscar in mi/h is given as

v =
`282 (km)/(h)` =
`282\left ( (km)/(h) \right ) \left ( (0.621 mi)/(1 km) \right )`

v = (282 x 0.621)
`(mi)/(h)`

v = 175
`(mi)/(h)`
