In the first 32 overs of a cricket match, the run rate was 7.2 runs/over. What is the required run rate in the remaining 18 overs to reach the target of 297 runs?

Total runs scored in 32 overs = 32 × 7.2 = 230.4

∴ Total runs to be scored in 18 overs = 297 – 230.4 = 66.6

$herefore$ Expected run rate $=frac{66.6}{18}=3.7$
