Answer 1

Answer:

255 miles

Step-by-step explanation:

The easiest approach to this is:

45 miles per hour for 2 hours means = 90 miles

55 miles per hour for 3 hours means = 165 miles

Total miles drove = 90+165 = 255 miles

Answer 2

Given :-

John left home and drove at the rate of 45 mph for 2 hours. He stopped for lunch then drove for another 3 hours at the rate of 55 mph to reach his destination

To Find :-

$\sf{Miles\: that\: John \:drive}$

Solution :-

Case 1 -

$\sf{Distance\: = Speed × Time}$

$\sf{Distance\: = 45 × 2}$

$\sf{Distance\: = 90 \:mph}$

Case 2 -

$\sf{Distance\: = Speed × Time}$

$\sf{Distance \:= 55 × 3}$

$\sf{Distance \:= 165\: mph}$

$\sf{Distance \:covered\: by\: John \:= 90 + 165}$

$\sf{Distance\: covered \:by \:John \:= 255\: miles}$
