A car travelled at a
constant speedof 40m/s
for 4.5 s. Calculate the
distance covered

180m

Step-by-step explanation:

you multiply 40 by 4.5 and get 180m

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
