In the first 20 overs of a cricket game, the run rate was only 2.4 per over. What should the run rate in the remaining 30 overs be to reach a target of 308 runs? [Give your answer correct to one decimal place.]

8.7

Sum of runs in 20 overs = 20 × 2.4 = 48

Total runs = 308

Sum of runs to be made in last 30 overs = 308 - 48 = 260

Run rate in last 30 overs should be = \(\frac{260}{30}\)

= 8.7 ( approx)
