उत्तर

S.No Speed Distance Time (Hours)
i 35 Km/hour 280 Km

Time = `"Distance"/"Speed"` km

= `280/35`

= 8 hours

ii 40 Km/hour 360 Km Time = `360/40` = 9 hours
iii 45 Km/hour 315 Km Time = `315/45` = 7 hours
iv 50 Km/hour 300 Km Time = `300/50` = 6 hours
v 55 Km/hour 275 Km Time = `275/55` = 5 hours
