Question

The mean distance that and Tina drove was 153 kilometers.If Ben drove 24 kilometers more than Tina,what was the distance that Tani drove?

Answer 1

141 km

Explanation:

Given data

Mean distance= 153km

Let Tina dirve=x km

Ben= x+ 24

Number of participants= 2

Hence,

Mean= total distance/number of participants

153= x+24+x/2

cross multiply

153*2= x+24+x

306 =2x+24

306-24= 2x

282=2x

Divide both sides by 2

x= 282/2

x= 141km

Hence Tina drove 141 km
