A scuba diver dives in a straight line from a boat to a coral reef.

Before the dive, the diver has 2300 litres of gas in his dive tank.

When diving from the boat to the reef, he uses an average of 5.3 litres of gas per metre travelled.

How much gas does the diver have in his tank when he reaches the coral reef?

Give your answer to the nearest litre.

Distance travelled: 28m + 137m = 165m

Answer :

Answer:

28m = 2141.6

137m = 1573.9

Step-by-step explanation:

for 28m you do 28 x 5.3 = 148.4 then you do 2300-148.4=2151.6

for 137 you do 137 x 5.3 = 726.1 then you do 2300 - 726.1 = 1573.9
