Convert. if necessary, round to the nearest tenth. (recall: 1 mi ≈ 1.61 km) km/h ~ 10 mi/h

10 mile per hour = 16.1 kilometers per h our

Step-by-step explanation:

We know that  

1 mile = 1.61 kilometers

We are supposed to convert speed given in miles per hour (mph) to kilometers per hours (kmph)

In order to do so ,  

1 mile = 1.61 kilometers

1 mile per hour = 1.61 kilometers per hour

Multiplying both sides by 10 we get

10 miles per hour = 1.61 *10 kilometers per hour  

10 miles per hour = 16.1 kilometers per hour

Hence our speed in kilometers per hour is 16.10 kmph

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.
