Last week, boris drove n miles. this week he drove 246 miles. using n, write an expression for the total miles he drove in 2 weeks

(n + 246 ) miles

Explanation:

Distance travelled in first week = n miles

Distance traveled in second week = 246 miles

Total distance travelled in two weeks = distance travelled in first week + distance travelled in second week

= ( n + 246) miles

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
